REFRIGERATING APPARATUS.

PECIFIGATION forming part of Letters Patent No. 281,793, dated July 24, 1883.

Application filed March 2-2, 1883. (No man.)

To all whom it may concern:

Be it known that I, J OSEPH REID, of Wyandotte, in the county of WVyandotte and State of Kansas, have invented certain new and useful Improvements in Refrigerating Apparatus, of which the following is a full, clear, and exact description.

The object of my invention is to effect more complete utilization of the cooling-power of air, of ammonia, or any other substance which, having been compressed, will absorb heat while it is expanding, particularly in that class of apparatus wherein the gas or ammonia is expanded 'in pipes immersed in any liquid that will not readily freeze, with the object of cooling said liquid, and thus preparing the liquid for refrigerating purposes.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan or top view of vats or tanks in which the cooling-coils are situated. Fig. 2 is a transverse section of a vat, showing the arrangement of coils, the section being taken on line x m, Fig. 1. Fig. 3 is a sectional elevation of Fig. 1 on line 3 y, showing the arrangement of flumes for conveying the liquid while being cooled. Fig. 4 is a sectional elevation of rooms, showing the arrangement of cooling-pans for passing the water from the lower part to the upper part of the rooms 5 and Fig. 5, a perspective view of cooling-pans,

showing the arrangement of cross-bars or weirs,

for obstructing the flow of the water and cansing it to overturn and circulate.

Fig. 1 represents a system of two vats or tanks, a, each separated into two divisions, b, for containing the liquid to be cooled, by means of coils c, in which the cooling liquid or gas is to be expanded, the liquid or gas entering the coil in the first division by the pipe-coir nections d, and, after circulating through it, passing to the next coil through pipe 6, and so on through all the coils, to be again compressed by a pump, 7', for returning again to the coils. The liquid to be cooled takes an opposite course from the expanding gas, and enters at esay from vat pand, after traversing the first division I), is delivered through fiume f fromthe bottom of the first division to the top of the second division, and may escape from the bottom of this division through flume g and pipe h to the first division of the next vat, and so on. WVhen the liquid is sufficiently cooled, it is pumped from the vat or division into which the gas first enters, andis delivered to the cooling-pans through pipe g, from which it is to be returned through pipe t to the vat p, to be pumped into the coolingvats by a pump, 1', or other means; but i11- stead of returning the gas directly to the compressor from the coils c, I propose to pass it through other coils in other vats containing water to be cooled for drinking or any purpose in less degree than is required for the re frigerating-liquid, thus utilizing its coolingpower to the greatest extent. \Vhen the re frigerating-liquid is to be used for cooling rooms, I propose to cause it to flow through a system of pans, 7c, placed one above another, beginning with the lowermost pan and delivering it to the next above successively, through the seriesby pumps Z, or other means for obtaining, the best results by passing the liquid from the coldest to the warmest part of the room. The pans are provided with cross-bars or weirs m, to maintain the proper quantity of liquid in them and effect constant circulation for taking up the heat.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the vats a, formed in divisions b b, the coils c, the pipes e, the fiumes f g, and the pipes h, as shown and described.

2. The combination, with the vats a, of the pipe q, the pumps Z, and the pans it, having cross-bars m, said pans being arranged one above another, as and for the purpose specified.

3. The arrangement of pans or conveyers one above another for causing the cold liquid to pass first along the lowest conveyer, and then along the various conveyers above in due order, and passing along the top one last, thus leaving the room from the warmest point
